INTRODUCTION: Symbiosis is the theme of this chapter as well as the theme throughout the world. Both organisms may benefit from the relationship or one organism may benefit while the other may suffer. When looking at life in the grand scheme, symbiosis is everywhere. It occurs within our own bodies as well as in many other organisms around the world. Evolutionary biologist, Toby Kiers, makes two valuable points when describing symbiosis. Kiers states that, “We need to separate important from harmonious. The micro biome is incredibly important but it doesn’t mean that it’s well balanced. Both partners may benefit, but there’s this inherent tension. Symbiosis is conflict – conflict that can never be totally resolved.”(Yong, 2016). There is…show more content…
Wolbachia virtually exists everywhere. Wolbachia symbiotic relationship with arthropods involves manipulating the host’s reproduction life. It acts as a reproductive parasite that manipulates the sex lives of its host to further its own end. The host, the arthropod, inevitably suffers, causing the relationship between the bacterium and host to be a commensalism relationship. Some hosts, like arthropods, may die, become sterile, or be unaffected in general. The mating pool can become very limited due to the effects of Wolbachia. One may say that Wolbachia is a bad bacterium, but it can possess some beneficial sides. In some species the bacterium may actually benefit the host. For example, the nematode worm, which apparently cannot survive without W. pipientis. It may also help flies and mosquitoes by preventing viruses and other pathogens attacking the host. Another example where the host benefits exist is bed bugs. Wolbachia acts as a nutritional supplement, creating B-vitamins. B-vitamins do not exist in the blood, which is consumed by the bed bugs; therefore, without the source of B-vitamins the bugs growth is stunted and they become infertile (Yong, 2016). Pannebakker et al. (2007) wanted to closely understand the symbiotic relationship between Asobara tabida, a wasp, and Wolbachia. To conduct this study, they first understood that A. tabida is naturally infected by three strains of Wolbachia. The research team decided to infect A. tabida with just the wAtab3
